Rainbow Deli and Grill Truck

I have met some chefs who spend many months designing the perfect food truck. They copiously design a theme, a website, a menu, a catchy name, a twitter feed, a schedule and some serious truck graphics before they design the first meal.
Or – If you can just get a hold of a used truck, swing by Ralphs for some food, go to Office Depot and spend about 30 bucks on poster board and 2-​sided tape, and to make it look like (as Winnie H told me) the Skittles truck exploded; and park where the real food trucks park. Best I can figure that is the business plan of the Rainbow Deli and Grill Truck.
I had a guacamole burger there today, and it was decidedly average. The guac, was three small avocado slices, not even mashed or spread over the top of the burger, and I was given a choice of «Fatburger Style» or lettuce, tomato and dressing (why not just say In-​N-​Out style?).
I chose Fatburger and got the usual basic condiments, especially relish. It was of a quality I would expect at a Carl’s Jr. It wasn’t awful, but it wasn’t memorable in any way shape or form.
